STEAM-JET BLOWER.

SPECIFICATION forming part of Letters Patent No. 787,279, dated April 11, 1905.

Application filed March 22, 1904. Renewed March 16, 1905. Serial No. 250.406-

Be it known that 1, CHARLES T. Con, a citizen ol" the l'nited States, and a resident of Kearney. in the county of lludson and State ot New Jersey, have mad and invented certain new and useful lmprovements in Steam- .let Blowers, of which the following is aspecilication.

My invention relates to an improvement in steam-jet blowers. the object of the same being to devise a device ol' this character which shall he simple and econon1i-al to manulacture and which shall be more ell ectivc than those now connnonly used.

\Yith these and other ends in view the inveutiou consists in certain novel features of construction, as will be hereinafter fully described. and pointed out in the claims.

In the accompanving drawings, Figure l is a top plan view ol a steam-jet blower constructed in accordance with my invention. Fig. 2 is a sectional view taken on the line 2 2 of Fig. 1. Fig. 3 is an end view thereof. Fig. l shows a moditied form applied to fur- 5 nace-doors, one door being open and the other door being closed. Fig. 5 is another modified lorm.

liel'erring to the drawings, A B represent two tubes or cylinders joined at their rear ends by means ot the web C and near their l'orward ends by the llange I), the latter be ing adapted to be bolted or otherwise secured to the wall ol the ash-pit below the furnacegrate in the usual manner. Between the 5 tubes and l'orward ot the tlange l) is the steam box or chest E, connecting the lorward ends of said tubes or cylinders and assisting in strengthening the union ol' the same. lnto the upper side ot said chest or box E is tapped the steam-supply pipe F, and l'rom the l'orward end of said chest or box leads the steam-pipe G, the latter being bil'urcated and bent baeltwardly, as illustrated in Fig. 1. the extreme end of each of the arms being provided with the nozzle ll, located centrally with respect to the tubes A and B in order to direct the steam into and through the latter, said pipe G being secured in place in the forward end o't said chest or box E by meansol the lock-nut [orother suitable fastening.

In practice. those portions of the tubes baclc of the llange I) are projected through the 'l'urnace-wall below the turnzwe-grate, said llange being secured to the wall itself, the forward ends ot the tubes and remaining portions ol the tubes projecting 'l'roln the trout side ot the wall and having supplied thereto st ram through the pipe F, which connects to the boiler at one end and to the steam-chest E at the opposite end, the cll'ect being that as the steam issues'lrom the nozzle H into and through the tubes A B it will carry with it a large quantity of air through said tubes and into the ash-pit below the [ire-bed. l

lt it is desired to attach the blower to the furnace-door, as is done in many instances, I provide the blower with tour tubes, as illustrated in Fig. -t, instead of two. In order to allow the door to swing open, it is necessary to form the tubes much shorter in length, and in such instance to secure the same amount of air with the short tubes it is necessary to increase the number thereol. It is evident, ol" course, that the tour tubes mayb 1 arranged in any desired manner with relation to each other, those in Fig. l (lettered K L M being arranged in a horizontal row joined together with webs, as in the case ol two tubes bcl'ore described, and having a steam-chest located between the two central tubes, a pipe leading thereto and pipe l. leading therefrom, the latter having branches, as illustrated in Fig. -l, and provided with nozzles It, located centrally with relation to each tube, the pipe 0 being provided with the swing-joint R, secured to the pipe S, leading lrom the boiler, in order to allow the door to swing open.

l t will be ulnlerstood, ol" course. that I do not limit my invention to the number of tubes employed nor to the relative arrangement thereot---as, lor instance, in Fig. I have shown one pair ol tubes U U, located above a second pair of tubes V V, the steamchcst being located between the tubes, as

in the case of the single pair shown in Fig. 1, a pipe and nozzle 10 being provided for each tube, as in the former instances.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A steam-jet blower, consisting of several tubes secured together at their front and rear ends, and connected by a steam-chest lo- I cated between the same, a steam-supply pipe leading into said steam-chest and an outletpipe leading from the latter and provided with a nozzle for each tube and located centrally with relation to the latter, substantially as described.

2. A stean1jet blower consisting of two parallel tubes secured together at their rear ends by means of a web and at their forward CHARLES T. COE.
